ESC
A straight line is drawn from x1,y1 to x2,y2 taking into account the graphics mode set
'V' (set/delete/inverse).
Example:
A straight line is drawn from 3,20 to 50,6.
ESC
Requests the area from the upper left corner (x1,y1) to the lower right corner (x2,y2). The graphics chip then
immediately sends the width and height of the image section followed by the image data. See the upload image
command ('U') for the structure of the image data.
Example:
The upper left part of the screen (32 x 16 pixels) is sent via RS-232.
ESC
Switches the tone off (n1=0), on for an undefined period (n1=1) or on for n1/10 seconds (n1=2..255). (This only
applies to versions with EA KIT240-7CTP and EA KIT240-7LEDTP touch panels.)
Example: $1B
The tone sounds for 1 second after this command.
ESC
Assigns an address to the KIT240 (add=0..254). The best place for this command is in the power-on macro.
Example: $1B
The KIT240 is assigned the address $01 with immediate effect.
ESC
Selects (S) or deselects (D) the KIT240 with the address add (0..254); the address 255=$FF is a master address
for all KIT240 units.
Example: $1B
All commands for the KIT240 with the address $01 are ignored with immediate effect.
ESC
Sets the link mode (n1) and pattern (pat) for the string
output text function (ESC Z).
Example: $1B
Sets the link mode for all subsequent text functions to
gray characters (pattern 3 = 50% gray) inverted with the
background.
Link mode n1:
1 = set: black pixels irrespective of the previous value (OR)
2 = delete: white pixels irrespective of the previous value
3 = inverse: changes black pixels to white pixels and vice versa (EXOR)
4 = replace: deletes the background and sets black pixels
5 = inverse replace: fills the background and sets white pixels
